Tailors time on Beijing Silk Street

In one of my trips I inquired at two stores for prices and time for delivery (I was specifically asking for a men's suit). The price (without bargaining) for a men suit (medium built size) I was told is around CYN 1000, they take all the important body measurements, the customer picks the fabric type, color and style. The manufacturing takes places overnight and is ready in 24 hours. I already thought that is fast. If you buy clothes at the Silk Street market, I suggest to go there and allows the opportunity to get back there at some other day if interested in exchange the product. I have bought silk pijamas, when I tried I realized I would like a slightly larger size, I went back the next day and I exchanged for the right size and colors (this means you know where you bought the product, there are too many stores and is easy to get confused if you don't pay attention). The staff had no problems exchanging the products for me (this time when I was back to the hotel and tried them, I was very happy with the results)
